Re: [Veritas-bu] Adding a DataDomain VTL need advice
Hi
We just finished adding DataDomain to our environment, and did not use
VTL. We use CIFS and NFS and
evertything is working fine.

We just did the same thing, end up tagging a DD690 onto a EMC storage bid
and got so focused on the storage bid that we overlooked the fact that the
DD690 as spec'd to us didn't include the FC/VTL option. Although honestly
I'm not sure that the VTL functionality would really be a plus. With the
CIFS/NFS configuration, it's simple matter to setup a disk storage or
staging unit to the DD690. No extra NB licenses costs involved either.
Just wish we had the FC bandwidth available to us.
In the couple weeks we've been using it, we've been seeing pretty
phenomenal
compression and de-dup rates.

Re: [Veritas-bu] Adding a DataDomain VTL need advice
Wayne, We have a couple of DD690s (1 Appliance, 1 Gateway) and I've really got only good things to say about them. They're easy to setup and configure (VTL and NFS). You might want to consider what your retention periods will be for the data you keep on it. We use 3 months max for the VTL, and anything over goes to Physical Tape for offsite storage. At www.datadomain.com there is a pointer to a Best Practices guide for Netbackup.

Re: [Veritas-bu] Adding a DataDomain VTL need advice
Make sure you understand that fibre for the Data Domain is an add on so costs extra. In our planning we were going to do fibre but didn't order the add on so ended up having to do GigE with NFS mounts instead. To get throughput we wanted we had to work on doing network aggregation. Having said all that the Data Domains work pretty much as advertised and the high compression/deduplication numbers are a reality.
